Have you ever ①feel a boring class lasted forever while an exciting weekend disappeared in an instant? This common experience reflects what psychologists call the distortion of time perception: subjective time can ②differ from actual clock time. Researchers explain that people who focus intensely on an enjoyable activity ③process fewer separate moments, so time seems to pass quickly. In contrast, bored or anxious people pay closer attention to each moment, ④making time feel as though it is dragging. When people become deeply engaged in a task, they often lose track of time, ⑤unaware of how many minutes have passed.

Time-management researchers frequently mention a principle ①known as Parkinson's Law, which states that work expands to fill the time available for its completion. According to this idea, a task that could be finished in one hour will often stretch to fill an entire afternoon if that much time ②is scheduled for it. Students who set vague deadlines frequently experience this effect, spending extra hours ③refined a report that was already complete. Employees given a full week for a simple project may also delay meaningful progress until the final days, even though the actual work ④requires far less effort. This pattern happens partly because people unconsciously adjust their pace to match perceived urgency. Setting shorter, more specific deadlines can counter this tendency, forcing tasks to fit within a tighter and more realistic window. By recognizing how flexible time encourages unnecessary delay, individuals can complete assignments more efficiently ⑤without sacrificing quality.

Psychologists who study daily behavior describe habits through a model called the cue-routine-reward loop. This theory explains that every habit ①begins with a cue, a signal that tells the brain to start an ②automatic behavior. The brain then performs a routine, which is the action itself, whether physical or mental. Finally, the brain receives a reward, a ③negative feeling that makes it want to ④repeat the same behavior. For example, a notification sound can act as a cue that leads a student to check a phone, and the relief from boredom becomes the reward. Similarly, opening a refrigerator out of habit rather than hunger shows how a routine can run almost without ⑤conscious thought. Because this loop operates automatically, breaking a bad habit requires changing the routine while keeping the same cue and reward. Understanding this structure helps people redesign daily patterns more effectively than relying on willpower alone.

Soyeon joined an online study group chat where dozens of students planned a class project together every evening. When one member suggested skipping a required survey step to save time, several others quickly agreed, and no one raised any objections. Soyeon privately worried that skipping the survey might weaken their project, but seeing everyone else nodding along, she stayed silent rather than risk sounding difficult. The group proceeded confidently, convinced their shortcut was harmless, until their teacher pointed out serious gaps once the project was submitted. Afterward, Soyeon learned about groupthink, a concept introduced by psychologist Irving Janis, describing how tightly connected groups often suppress doubts in order to maintain harmony and reach quick agreement. She realized that ___________.

Imagine two factories making the same product: one in a country with strict carbon rules, and one in a country with almost none. (A) However, critics claim it unfairly burdens developing countries, which often lack money to modernize factories quickly. For example, a small exporter in a poorer nation might struggle to pay the added charge, though it contributes little to global emissions. Still, if wealthier nations pair the policy with technical support, it could become a genuinely fair tool for cutting emissions worldwide. (B) Supporters argue that the system protects domestic industries and pushes foreign manufacturers toward cleaner methods. (C) The factory facing stricter rules often spends more, which can make its goods pricier than those made elsewhere. To fix this imbalance, some governments have introduced the carbon border adjustment mechanism, a policy charging imported goods a fee based on how much carbon was released while producing them.

This process, though it may sound simple, triggers a remarkable series of adaptations throughout the cardiovascular system. Aerobic exercise, such as jogging, swimming, or cycling at a steady pace, strengthens the heart by forcing it to pump larger volumes of blood with each beat. ( ① ) Over weeks of consistent training, the heart gradually enlarges and becomes more efficient, meaning it can deliver the same amount of oxygen to working muscles while beating fewer times per minute. ( ② ) This adaptation explains why trained athletes often have a much lower resting heart rate than sedentary individuals of the same age. ( ③ ) Beyond the heart itself, aerobic activity encourages the body to build new capillaries within muscle tissue, improving the delivery of oxygen and nutrients at a cellular level. ( ④ ) Researchers have also found that regular aerobic exercise reduces inflammation throughout the body and improves the way cells respond to insulin. ( ⑤ )

주어진 문장: This gap between image and reality is precisely what makes the practice so misleading. Many companies now advertise themselves as environmentally responsible, yet a growing number of these claims turn out to be misleading. ( ① ) This practice, known as greenwashing, occurs when a business spends more effort marketing its products as eco-friendly than actually reducing environmental harm. ( ② ) A company might launch a recycled-packaging line while continuing to pollute rivers through its main factories, creating a false impression of genuine change. ( ③ ) Such tactics deceive well-intentioned consumers who wish to shop responsibly but lack the tools to verify corporate claims. ( ④ ) In contrast, truly sustainable businesses publish detailed, independently verified data about their emissions and supply chains, allowing outsiders to check their progress. ( ⑤ ) Therefore, shoppers should look beyond vague labels like green or natural and instead search for recognized certifications, transparent reports, and measurable targets. Without such scrutiny, greenwashing will keep flourishing, undermining public trust and slowing the broader shift toward an economy that truly protects the planet.

주어진 문장: Even a short break from checking their phones can trigger a nagging sense of unease. Many teenagers check their social media accounts dozens of times a day, worried that they might miss something important happening among their friends. ( ① ) This anxiety, known as FOMO, or the fear of missing out, arises when people believe that others are enjoying experiences from which they themselves are excluded. ( ② ) For example, a student scrolling through photos of a party she was not invited to may suddenly feel a wave of loneliness and regret, even though the event has already ended. ( ③ ) Constantly refreshing feeds to avoid missing such updates, however, makes it difficult to concentrate on schoolwork or conversations happening in the present moment. ( ④ ) Moreover, this endless comparison with curated highlights of other people's lives tends to deepen feelings of anxiety rather than relieve them. ( ⑤ ) Therefore, students should learn to limit their social media use and focus more attention on the relationships and activities directly in front of them.

Because this feedback loop relies entirely on light rather than on the clock on the wall, melatonin release can shift dramatically when a person travels across time zones or works through the night. Melatonin is a hormone produced by a small gland deep within the brain, and its release follows a remarkably predictable daily pattern. ( ① ) Levels stay low throughout the bright hours of the day, begin rising in the evening as darkness falls, peak in the middle of the night, and then decline again as morning approaches. ( ② ) This rhythm is controlled primarily by light: specialized cells in the eye detect brightness and send signals that either permit or suppress melatonin production, which is why exposure to bright screens late at night can delay its release and make falling asleep more difficult. ( ③ ) Unlike some hormones that directly cause the body to perform a task, melatonin does not force sleep to occur; instead, it signals to the rest of the body that night has arrived, preparing various systems to shift into a lower-energy state. ( ④ ) Because of this signaling role, taking melatonin supplements at the wrong time can shift a person's internal clock in the opposite direction from what was intended. ( ⑤ )

In short, an effective fueling plan treats carbohydrate loading as one tool among many, not a substitute for well-rounded nutrition. In the days leading up to an endurance event, many athletes deliberately increase their carbohydrate intake while reducing training volume, a practice known as carbohydrate loading. ( ① ) The strategy is designed to maximize the amount of glycogen, the storage form of carbohydrate, packed into muscle tissue before competition begins. ( ② ) Because glycogen serves as the primary fuel source during prolonged, intense exercise, entering an event with fuller stores can delay the point of exhaustion that runners often call hitting the wall. ( ③ ) Sports nutritionists caution, however, that the timing and composition of meals matter as much as the total quantity of carbohydrate consumed, since eating unfamiliar foods immediately before competition can cause digestive discomfort. Athletes are therefore advised to practice their nutrition strategy during training rather than experimenting with it for the first time on race day. ( ④ ) Beyond carbohydrates, adequate protein and micronutrient intake throughout the training cycle remains essential, since fueling strategy is only one part of a much larger nutritional picture.
